1
Q
The law of conservation of mass
A
Mass of reactants = mass of products
2
Q
What is avegadro’s constant
A
1 mole of anything has 6.02 x 10^23 particles in it.
So to find 1 mole of a compound without knowing the mass you do: RFM x 6.02 x 10^23
3
Q
What are the two equations for concentration
A
Concentration (mol/dm^3) = mols (mol) / volume (dm^3)
Concentration (g/dm^3) = amount of substance (g) / volume of solution (dm^3)

Q
Equation for % yield
A
(Actual yield / theoretical yield ) x 100
